Socket welding
Socket weld flanges are connected to pipes using a single fillet weld executed on the outer side of the flange (different from the slip-on flange type that requires two welds).
Socket Weld Flanges are used for small-size and high-pressure piping that do not transfer highly corrosive fluids.
